Make the Eocene not hot and wet? I thought a global climate that is hot and wet is what allows an explosion of diversity to happen. It seemed the case in the Eocene, and again in the Miocene.


I didn't stop the Permian extinction--just delayed it, toned it down and gave it a different style.

Any global climate allows for an explosion of diversity, just in different places. A hot and wet climate creates an explosion of diversity in the tropics, but also tends to create equally large deserts. While a cold and dry climate creates plenty of diversification for areas above or below 60 N/S respectively.

Also depends on the continental layout. In a more ancient continental layout, there were a lot of inland seas, these create opportunities for moisture. Compared to being in the center of a continent or surrounded by mountains like Kansas or Nevada.
